Abstract

Le mauvais alignement des électrodes internes provoqué par compression-liaison peut être empêché, et une pièce de bobine multicouche fabriquée efficacement et son procédé de fabrication sont proposés. Une pièce de bobine multicouche (1) comprend un corps multicouche (2) où des couches de matériau magnétique (4, 5, 6) sont formées et une bobine (L) composée d'électrodes internes (7) et incorporée dans le corps multicouche (2). Le nombre de couches de matériau magnétique (4, 5, 6) formées dans une région de non-chevauchement (E) où elles ne se chevauchent pas avec les électrodes internes (7) dans la direction de l'empilement est supérieur à celui des couches de matériau magnétique (4, 5) formées dans la région de chevauchement (D) lorsqu'elles se chevauchent avec les électrodes internes (7) dans la direction de l'empilement.
